Incazelo yomkhiqizo we-DIMETHYLUREA
I-1,1-Dimethylurea iyinhlanganisela yamakhemikhali ene-molecular formula C3H8N2O.Yaziwa nangokuthi i-dimethylurea noma i-DMU.Yimpushana emhlophe ecwebezelayo, encibilika kalula emanzini nasezincibilikisini eziphilayo.
I-1,1-Dimethylurea inezinhlelo zokusebenza ezihlukahlukene ezimbonini ezahlukene.Okunye ukusetshenziswa kwayo okuyinhloko njenge-reagent ku-organic synthesis.Ngokuvamile isetshenziswa njengomthombo we-dimethylamine, isakhiwo esibalulekile sokwakha ekukhiqizeni imithi, odayi namanye amakhemikhali.
Embonini yemithi, i-1,1-dimethylurea isetshenziswa njengesandulela sokuhlanganiswa kwezidakamizwa kanye nabaphakathi kwezidakamizwa.
Ingasetshenziswa njenge-ejenti evikelayo yamaqembu asebenzayo azwela amakhemikhali ngesikhathi sokusabela kwe-organic.Ibuye isetshenziswe njenge-catalyst ekuphenduleni okuthile.
Ngaphezu kwalokho, i-1,1-dimethylurea nayo isetshenziswa ekuhlanganiseni ama-herbicides nama-fungicides.Isebenza njenge-stabilizer futhi ithuthukisa ukusebenza kwalawa makhemikhali ezolimo.Kubaluleke kakhulu ukuphatha i-1,1-dimethylurea ngokucophelela ngoba ibhekwa njengeyingozi uma idliwe noma ithinta isikhumba noma amehlo.Izinyathelo zokuphepha ezifanele kufanele zithathwe lapho usebenza nalesi sithako, njengokugqoka izinto zokuzivikela kanye nokuqinisekisa ukuthi kungena umoya omuhle.
Kafushane, i-1,1-dimethylurea iyinhlanganisela yemisebenzi eminingi engasetshenziswa ku-organic synthesis, imithi, kanye namakhemikhali e-agrochemicals.Izakhiwo zayo ziyenza isebenziseke njenge-reagent, isivikelo, kanye ne-catalyst ezinhlobonhlobo zezinqubo zamakhemikhali.

Ukusetshenziswa kwe-DIMETHYLUREA kanye ne-Synthesis
| Chemical Properties | Impushana yekristalu emhlophe ukuya kokumhlophe |
| Isebenzisa | 1,1-Dimethylurea (N,N-dimethylurea) isetshenziswe ku-Dowex-50W ion exchange resin-promoted synthesis ofN,NI-'-disubstituted-4-aryl-3,4-dihydropyrimidinones. |
| Incazelo evamile | Izakhiwo ze-optical ezingaqondile ze-1,1-dimethylurea (N,N′i-dimethylurea), ihlolwe ngesizukulwane sesibili se-harmonic. |
| Ukuvutha nokugqama | Akuhlukaniswanga |
